topic to analyze this code is located in Cga_putc, CGA_PUTC is divided into three parts, the first part is based on the character value of int C to determine exactly what to look like. And the second part is the above code. The third part is to display the characters you decide to display to the specified position on the screen. Let's analyze the second part concretely, When Crt_pos >= crt_size, where crt_size = 80*25, since we know that the Crt_pos value range is

We will discuss them separately:Anonymous Functions In functional programming languages, a function can have no name. An anonymous function usually indicates "a piece of code that can accomplish something ". This expression is useful in many cases, because we sometimes need to use a function to accom

Fermat theorem (Fermat theory) is an important theorem in number theory: if P is prime, and gcd (a,p) = 1, then a(p-1) ≡1 (mod p). That is: If A is an integer, p is a prime number, and A,p coprime (that is, there is only one convention of 1), then the remainder of a (p-1) di
